7. You are given the following set of stocks, their prices and their shares outstanding over a one day period a. (10 pts) Create a value-weighted index using the Open price as the initial index value (100). What will the index be at close and what will the return be? b. (10 pts) Create an equally weighted portfolio using the Open Price to set the initial weights. What will the return to the portfolio be at the end of the day? (If it makes it conceptually easier you may assume you have 10000 and purchase fractional shares to set up the initial portfolio)
